nfsd

Which nfsd is used by NFS/TCP?

The nfsd process used by NFS/TCP has a parent process ID of 1 (init)

and has no child processes. In this example – TID 1829 (PID 1809).

Looking at the above screen output, you see the entire list of daemons and kernel

threads used for servicing NFS/UDP and NFS/TCP requests. The nfsds responsible

for servicing UDP requests are using TID numbers 1833, 1834, 1836, and 1840.

The nfsd process used for managing NFS/TCP connections is distinguishable from

the NFS/UDP nfsds by the fact that it has a parent process ID of 1 (init) and it has

no child processes. In the above screenshot, there is only one nfsd daemon that

meets these criteria – the one using TID 1829 (process ID 1809).

There are currently four nfsktcpd kernel threads servicing NFS/TCP requests –

18306, 18340, 18523, and 18529. Finally, there is the nfskd daemon, which

currently serves no purpose on HP-UX systems.
